+  <strong>AWS S3 vs. third‑party S3:</strong> When using AWS S3 directly, leave `S3_ENDPOINT_URL` unset and

+Formbricks uses the S3 [POST Object](https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPOST.html)

+S3‑compatible API currently does not support POST Object and therefore will not work with Formbricks file
+uploads.
